Collection: Theses (Master's degree) - Physics / วิทยานิพนธ์ – ฟิสิกส์Type: Thesis(Silpakorn University, 28/6/2024)This research utilizes tin dioxide nanoparticles as gas detection materials, synthesized through a simple precipitation process, and added vitamin C as a capping agent in varying amounts of 2%, 5%, and 10% to adjust particle ... -
DEPLETION OF SOLAR ULTRAVIOLET RADIATION BY AEROSOLS DURING CLEAR SKY CONDITIONS FROM DATA COLLECTED AT NAKHON PATHOM STATION AND STATISTICAL CHARACTERISTICS OF AEROSOLS FROM MEASURING STATIONS IN THAILAND
Collection: Theses (Master's degree) - Physics / วิทยานิพนธ์ – ฟิสิกส์Type: Thesis(Silpakorn University, 4/7/2023)In this work, depletion of solar ultraviolet (UV) radiation in wavelength between 260 - 400 nm by aerosols under clear sky conditions at Nakhon Pathom station (13.82 °N, 100.04 °E), a solar monitoring station in Thailand, ... -
Development of a model for calculating global spectral solar irradiance under all-sky conditions in Thailand
Collection: Theses (Ph.D) - Physics / ดุษฎีนิพนธ์ - ฟิสิกส์Type: Thesis(Silpakorn University, 4/7/2023)This thesis presents a model for computing global spectral solar irradiance under all-sky conditions in Thailand. The model expresses the global spectral irradiance under all- sky conditions as a multiplication of two ...
